Using Test Drilling to Sample Gold Deposits

Apr 27, 20160183;32;Test drilling for gold is an important step in prospecting and eventually commercially mining for gold. Test drilling is done to get a continuous sample of the bedrock of a given gold project. The sample is then tested to determine if there is gold in the project area and to estimate the amount of gold that can be mined in the area.

How does natural gas drilling work? HowStuffWorks

To get the most gas possible, after drilling a hole, energy companies line the hole with materials meant to keep the gas in. Next, they send electric charges down the well, which affect the rock around it. After the charges are set off, a highly pressurized liquid fracking solution is sent down the well.
